ElliottDavis Posted August 20, 2018 Share Posted August 20, 2018 Hi guys. Last week i was driving my car quite hard and my engine light came on. My fault reader came up with P1274 - Air/fuel ratio sensor 1. About 2 weeks ago I took my throttle body and air intake off for a clean as it was filthy and wasn't running quite right. Drives fine now but as I took the throttle body of it came clear to me that it's probably a 'one fit' gasket which I didn't replace. Anyway looking into the different reasons why this code would come up ive seen that the car running rich (too much air to fuel) can be due to intake gaskets.. would that really be enough to throw a code a week or 2 later? These are the possible faults: Faulty Air fuel ratio (A/F) Sensor 1 Bank 1 Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection Fuel pressure Faulty Fuel injector Faulty Air Flow Meter Hoping its not an injector! Cheers guys! Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted August 20, 2018 Share Posted August 20, 2018 You have it around the wrong way: If your car is running rich you have too much fuel to air. I have all the parts in stock to fix your list of possible faults. The gasket for the TB is reusable providing it is not damaged. Just drop me a PM if I can help further. Alex.
